Step 4: Fasten I-beam to uprights.
[NOTE: Shim only used with models AHSN-6-20-12, 6-20-14, 6-20-16, 8-20-12, 8-20-14 & 8-2016.]
a. Insert the flange of the I-beam into the gap between the beam clamp and the top of the uprights (see FIG. 4B
below);
b. Then clamp the flange on the opposite side of the beam to the beam bracket with the remaining beam clamps
as shown in the diagram below.

Step 5: Tighten the beam clamp nuts and bolts to 50 - 52 ft·lb of torque.
Step 6: Put the crane on its feet.
Rotate the crane onto its feet in a controlled manner. For instance, attach a hoist chain to the I-beam and slowly
raise the beam until the crane stands on its feet. Alternatively, raise the crane with a fork truck. Position the forks
under the I-beam and slowly raise the beam until the crane rotates onto its feet in a controlled manner.
Approach the crane with
a fork truck from this side
and slide the forks under
the I-beam.
Slowly raise the beam
and drive forward until
the crane stands on its
feet.
